2 Claims.

This invention relates to cans or receptacles more particularly of the frictionplug closure type, to a sealing closure therefor, and to the process of making such cans and resides more particularly in the construction of the head or end of the can; in the association and relationship of a radially extending part of said head or end with the opposed adjacent inner wall face portion of the can body; in the location of, and means for securing, the seal; and in the process of drawing or forming such can end or head, as well also as in the can end or head per se as a completed article of commerce.

The primary objects of this invention are to provide a can or receptacle of the type mentioned with a head or end which will have a depending opening wall to be engaged by the friction plug and which will be provided with a radially outwardly extending flange extending from substantially the lowermost portion of said opening wall to a point closely adjacent the adjacent portion of the inner face of the body of the can, approaching so close to the latter as to prevent articles contained in the can from jamming between the outer edge face of the flange and said inner face of the body, or between any part of the head or end and the inner face of the body; to provide a can end or head of the type mentioned with the usual upper web or flange extending from the top seam radially inward to the closure opening in combination with a wide reinforcing flange extending radially outward from the lower portion of the wall of the closure opening for nearly the same distance as the upper web or flange to a point closely adjacent the inner wall of the body whereby the head will be greatly reinforced and strengthened, and to, provide a process whereby such ends or heads may be progressively stamped or drawn up from suitable stock sheet metal without excessive wastage and of substantially uniform condition with a radially and peripherally continuous integral lower or inner radially outwardly extending lower flange of exceptional length in a radial direction. Further objects are to so'form said lower flange as to adapt it for easy and efficient association and cooperation with a suitable preferably aluminum foil frangible sheet to provide an air and fluid tight closure or sealing of the upper end or head of the can; to provide a very simple efiicient hermetically sealed can end or head; to provide suchv can ends or heads, either with or without the frangible sheet applied thereto, as complete articles of ,manufacture ready for application by packers or others to the containers employed by such packers, whether'such containers be of metal, paper, wood, glass or of other materialyand either in its preferred'integral form', or in any one of several modified forms. j

Figures 1 and 2 are made to exact scale from corresponding blanks and parts of a can as actually made and now in extensive commercial use. p

.Referring now in detail to the drawings, A designates the outer or seam portion of the end or head, B the usual vertical flange or shoulder making a snug fit in the end of the body E, C the usual radially inwardly extending top flange or web extending radially inward to the top of the wall D of the closure opening, I the lower flange extending outwardly from the extreme lowerend or portion of a collar 2, the collar 2 making'a snug friction fit about the outer face of the wall D of the closureopening, and said wall D and collar 2 are curved or bent in the direction of their common axis to lock them'together Preferably the radially outer portion A of the end or head and the upper portion F of the body E are seamed together in such manner that the portion A interlocks with or hooks under the portion F, and the portions J of the bottom K and H of the lower end of the body E may be similarly seamed together by the packer after the can has been filled. The foregoing brief reference to the seaming of the head and bottom to the body applies to all modified forms equally as well as to the preferred form.

Likewise, both in the preferred form and in each of the modified forms, the upper flange or web C may be of ribbed or corrugated form as shown or of a continuous convex or concave form or perfectly flat or of such other form as may be desired, this feature per se forming no part of my present invention.

As applied to the can body E the can end or head is to be provided with the internal lower flange I extending from the lower part of the closure opening wall D radially outward preferably substantially perpendicularly to the axis of said head and body to a point so closely adjacentthe opposed inner face of said body as to prevent the entry therebetween of the articles, or any of the articles, contained in the can, as more clearly illustrated in Fig. 2, wherein cigarettes contained in the can are indicated in dotted lines. At the same time, said flange I should not extend radially outwardly quite as far as the outer face of the vertical or marginal flange or shoulder C as otherwiseit would interfere with the ease of assembly of the end or head on the can body E, involving eXcessiVetime in the assembly operations and increasing production costs to a prohibitive point, but should extend radially outwardly as far as possible without interfering with assembly operations, and having the foregoing considerations in view I have found that a clearance-at all points of about one-sixteenth (1 to three-thirty-seconds (3%) of an inch between the radially outer edge of said flange l and the opposed inner face of'the'body E gives ample clearance to avoid any difliculty or slowing up in the assembly operations while effectually preventing the entry of the end of any of the contained cigarettes between'said flange l and the inner face of the body E.

This flange l while preventing the wedging of the ends of any of the contained articles between the inner face of the can and the opposed radially outer edge of the flange I, also serves to very greatly strengthen the end of the can as a whole, whereby lighter metal stock maybe used without any sacrifice in the ultimate strength of the can end or head as a whole, thus making it practical to produce a stronger can without any increase in the expense of materials or as strong a can with a saving in the amount of metal employed.

If desired a frangible seal, preferably a sheet aluminum alloy such as now known to the trade, and of proper size, or taggers tin or other soft metal or other suitable sealing closure means, 3 may be applied against the bottom face of the flange l and have its marginal portion 4 folded or spun about the radially outer edge of flange-l and across the upper face thereof closely adjacent to the outer face of the closure wall D, as illustrated for instance in Figures 7 and 8. If this frangible seal 3 is to be used it will be applied to the flange l of the can end or head before the latter is seamed to the can body E. Also, the can ends or heads as thus formed, either with or without the frangible seal 3 applied thereto according as may be the desire of the customer, may be sold separately as finished articles of commerce to other can manufacturers or packers or to others desiring the same for use in connection with receptacle bodies such as they may prefer and in accord with the needs and exigencies of their manu facturing and packing operations.

In the modification shown in Figure 4 the cons'truction and operation are thesame as in the form shown in Figure 3 except that the closure wall D is more pronouncedly cone shaped and the collar 2 is correspondingly coned, the collar '42 being forced onto the outer face of the wall D with considerable pressure to give a very tight frictional grip, the flange l extending radially.

outwardly from the lower portion of the collar 2.

In the modification shown in Figure 5 the construction and operation are the same as in the form shown in Figure 4 except that the closure opening wall D has less taper than in Figure 4, or none at all, the: collar 2 is correspondingly formed and driven onto the wall D exteriorly thereof and said collar and wall are then interlockedby impressing indentations. 5 therein, the flange I extending radially outwardly from the lower portion of collar'2 In the modification illustrated in Figures 6 and '7 the construction and operation are the same as: that of the form illustrated in Figure 4,. except that the sealing closure 3 has its marginal portion 30 extending between the opposed faces of the collars D and 2 and tightly clamped between said faces with a tight frictional fit, the operation of driving these collars together serving to stretch the seal 3 tightly across the discharge opening defined by the collar D and to wedge the marginal portion 36 of the seal 3 between the opposed faces of the collars D and'Z with an air-tight fit.

The cans illustrated in Figures 8 and 9 may be constructed in accordance with any one of the several modified forms illustrated in Figures 3' to 5 inclusive and may have their seals 3 applied according to the manner shown in Figures 3 and 4 or in the manner shown in Figure 7;

I Likewise the seal 3 may be applied in any one of the several ways herein illustrated to any one of the several forms of'the invention herein illustrated.

A suitable friction closure plug P indicated in light broken lines in Figure 1 is of course to, be used in association with the can end or head, as usual, and will be of such shape as to properly cooperate with the particular construction of can end or head, either in its preferred form or in one of its modified forms such as illustrated'.

Of course in all views, including Figures 1v to 2 inclusive which otherwise are made to exact scale'as stated, the thickness of the metal stock used is greatly exaggerated in order to clearly show the same in section.

I claim:

1. A' receptacle comprising a body and a head suitably secured to said body to close one end thereoflsaid head having an imperforate web and a wall depending from said web and defining the usual discharge opening, in combination with a collar disposed about said wall, an imperforate frangible closure seal extending across the area defined by said wall and'having its marginal portion clamped with an air-tight frictional engagement between theopposing faces of said wall and collar, and a flange integral with said collar disposed substantially perpendicularly to the axis of said collar and extending therefrom outward to such distance that its outer edge will be located at all points so closely adjacent tothe inner face of said body as to prevent articles contained within the receptacle from working between said body and said outer edge of said flange.

2. A receptacle comprising a body and a head suitably secured to said body to close one end thereof, said head having an imperforate web and a wall depending from said web and defining the usual discharge opening, in combination with a collar snugly engaging and held to said depending wall, and a flange integral with said collar disposed substantially perpendicularly to the axis of said collar and extending therefrom outward to such distance that its outer edge will be located at all points so closely adjacent to the inner face of said body as to prevent articles contained within the receptacle from working between said body and said outer edge of said 10 flange.
